UNITED STATES PATENT OFFICE.

RUSSELL F. AVERY, OF SPOKANE FALLS, WASHINGTON, ASSIGNOR TO JACOB GOETZ,OF SAME PLACE.

DEVICE FOR OPERATING PUMPS BY MEANS OF READLES.

SPECIFICATION forming part of Letters Patent No. 482,777, datedSeptember 20, 1892.

Application filed August 5, 1891. Renewed July 19,1892. Serial No.440,520. (No model.)

To all whom it may concern.-

Be it known that I, RUSSELL F. AVERY, a citizen of the United States,residing at Spokane Falls, in the county of Spokane and State ofWashington, have invented a new and use ful Treadle Connection forAutomatically and Simultaneously Opening and Closing theDispensing-Fauoet and the Pressure-Valve of a PneumaticLiquid-Dispensing Apparatus, of which the following is a specification.

The object of my invention is to provide means whereby a faucetcommunicating with a vessel containing liquid and the valve of apneumatic or other pump supplying an airpressure to said vessel maybeautomatically and simultaneously opened and closed by means of afoot-treadle, giving the person operating said device the free use ofhis hands.

My invention consists of a treadle pivoted to a lever of the firstclass, one arm of said lever being connected with a faucet communicatingwith the vessel from which the liquid is to be drawn and the other armof the lever with the lever of the pressure-valve in an aircompressorconnected with said vessel.

In the accompanying drawings, which illustrate my invention, I haveshown the lever and treadle as applied to the liquid-dispensingapparatus described in my application for Letters Patent filed April 13,1891, Serial No. 388,770; but I do not limit myself to its use with thisparticular construction, as it may be used with any pump orair-compressor.

Figure 1 is a view of the same in combination with the compressor andliquid-containing vessel, and Fig. 2 is a view of the treadle as appliedto the faucet alone.

A is a vessel containing the liquid to be drawn.

B is a faucet communicating with the ves- H with the arm (I of thepressure-valve D.

I is an arm, which is connected by the spring twith the pressure-valvearm d.

K is a treadle suspended by the link is to one arm of the lever F.

The operation of the device is as follows:

In its normal position, as shown in Fig. 1, both the faucet B is closedand the valve D is turned off, so that no pressure is admitted to theair-pump C, as described in my application above referred to. IVhen thetreadle K is pressed down by the pressure of the foot,

it and its connections take the position shown in dotted lines in Fig.1, opening the faucet B, and at the same time the pressure-valve D,which causes the air-pump to force air into the vessel A and the liquidto How from the dispensing-faucet B. As soon as the required amount ofliquid is drawn, on removing the foot the spring 1 draws back the leverd, and with it the lever F, to its first position, simultaneouslyclosing both faucet and valve.

I do not limit myself to the particular means for connecting the arms ofthe lever F to the valve and faucet, nor to the use of a spring 7 foreffecting the automatic closing, as a counter-weight may be used as anequivalent, nor to the particular location of the spring, as thesedetails may be greatly varied without departing from the spirit of myinvention.

Should it be desired to use my invention with the faucet alone, thechain H can be omitted and that arm of the lever F attached by thespring 2' immediately to the floor, as shown in Fig. at. I thus providean automatic 85 treadle operated device which opens and closes a faucetand the pressure-valve of the pump at one operation, absolutely preventsthe careless leaving open of the faucet, and is under the immediatecontrol of the person 0 attending the device, while giving him the freeuse of both of his hands.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In an apparatus for dispensing liquids, the combination, with thefaucet of the liquid-containing vessel and the pressure-valve of theair-pump connected therewith, of a centrally pivoted lever, suitableconnections betoo tween the arms of the lever, respectively, with thefaucet and pressure-valve, a treadle attached to saidlever, and a devicefor automatically raising the lever after the treadle has beendepressed, substantially as described.

2. In an apparatus for dispensing liquids, the combination, with thefaucet B, communicating with the liquid-containing vessel A, of the armb of the faucet, the pivoted lever F, the rod G, connecting, one arm ofthe lever F with the arm b of the faucet B, the treadle K, pivoted tothe lever F, and means for automatically raising the1ever,substantiallyas described.v

3. In an apparatus for dispensing liquids, the combination of the faucetB, communieating with the liquid-containing vessel A,

the arm I) of the faucet, the pressure-valve D of the pump 0, the arm (1of the pressurevalve,the lever F, the rod G, connecting one arm of thelever F with the arm I) of the fancet, the chain H, connecting the otherarm of 20 to a fixed support, substantially as described. 25
